Civil War Medicine
Also of significance are the institutions which were founded in the Civil War’s aftermath: the National Institutes of Health, the National Library of Medicine, and the Index Catalogue of the Surgeon-General’s Office, the pre-cursor to the modern MEDLINE.
The National Library of Medicine offers a couple of Civil War exhibits:
Life and Limb: The Toll of the American Civil War (2011)
Binding Wounds, Pushing Boundaries: African Americans in Civil War Medicine (2010)
